So I picked up Ninja All Stars mainly for the SDE stuff. I'm working on painting it up first. I spent some time rebasing them as well so they are on SDE bases instead of the thinner NAS ones. Here is the Hidden Shrine Mystic first. I wanted him to be very simple, as a wandering priest would be. His basket was fun to paint.

As for my technique, I give everyone a black prime. Then I paint around the recesses to leave those black outlines. I try to use very vibrant colors. Then once the basecoat is done, I do 2 levels of highlights. Takes some time, but it's well worth it.
